DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figures 1-5 The utility model provides a technical scheme:

[0025] Embodiment one:

[0026] A fixed type beam bottom inspection vehicle, including bearing plate 3, bearing plate 3 top is provided with bridge 1, bearing plate 3 upper end face left and right sides are symmetrically provided with lifting assembly 2, and lifting assembly 2 is used to lift and transport inspection personnel, so that inspection personnel can conveniently walk to or leave bearing plate 3, bearing plate 3 upper end face front and back sides are symmetrically provided with protection assembly 4, and protection assembly 4 is used to protect the inspection personnel walking on the upper end face of bearing plate 3, to avoid the inspection personnel walking on the upper end face of bearing plate 3 from falling, bearing plate 3 bottom middle position is fixedly connected with counterweight seat 31, and counterweight seat 31 can exert a certain pull-down force on the middle region of bearing plate 3, so that the stability of bearing plate 3 is better during movement and use.

[0027] The lifting assembly 2 includes a support frame 21, an electric hoist 22, a connecting wire rope 23, and a transport car 24. The support frames 21 are symmetrically arranged on both sides of the upper surface of the bearing plate 3. The support frames 21 are connected to the bearing plate 3 by welding. The support frames 21 are concave in shape, which not only supports the electric hoist 22 but also does not affect the lifting of the transport car 24. The electric hoist 22 is installed on the top of the support frame 21, and the transport car 24 is installed inside the support frame 21. 4. Two sets of transport cars 24 are installed, and the two sets of transport cars 24 are of the same specifications. The distance between the two sets of transport cars 24 is slightly larger than the width of the upper end face of the bridge 1. The transport cars 24 are connected to the electric hoist 22 by a connecting wire rope 23. When the electric hoist 22 is working, it can drive the transport cars 24 to rise and fall through the connecting wire rope 23 so that the transport cars 24 can lift and transport the inspection personnel. Since the detailed working principle and internal structure of the electric hoist 22 are relatively mature technologies in the existing technology, they will not be described in detail here.

[0028] The inner wall of the support frame 21 has a limiting vertical groove 25, and the side of the transport car 24 is provided with a limiting block 26. The limiting block 26 is connected to the transport car 24 by welding. The limiting block 26 matches the limiting vertical groove 25. The matching limiting block 26 and the limiting vertical groove 25 prevent the transport car 24 from shaking or deviating during lifting and lowering, thereby ensuring the lifting and lowering stability of the transport car 24. The outer side of the inner wall of the transport car 24 has an insertion hole (not shown in the figure). The insertion hole allows the subsequent inspection personnel to insert the external guardrail door into the interior of the transport car 24 for blocking and protection as needed.

[0029] A control box is installed on the inner wall of the transport car 24. Figure 4 (As shown in the diagram), the control box contains a control panel and a servo motor 9 controller. The input of the control panel is connected to an external fixed power supply via a wire, and the output of the control panel is connected to the electric hoist 22 via a wire. The input of the servo motor 9 controller is connected to an external fixed power supply via a wire, and the output of the servo motor 9 controller is connected to the servo motor 9 via a wire. The control box, which contains the control panel and the servo motor 9 controller, allows inspectors to control the servo motor 9 and the electric hoist 22 separately as needed. Since the detailed internal structure and working principle of the control panel and the servo motor 9 controller are relatively mature technologies, they will not be described in detail here. The control box door is equipped with a concealed lock, which allows inspectors to lock the control box door to prevent unauthorized personnel from opening the control box.

[0030] Example 2:

[0031] On the basis of embodiment one, the blocking vertical rods 41 and the blocking horizontal rods 42 are fixedly connected in this embodiment, which can form a guardrail to block and protect the inspectors walking on the upper end surface of the bearing plate 3. After the safety rods 43 are connected with the safety hooks, the safety rods 43 will not hinder the movement of the safety hooks following the inspectors, so that the inspectors standing on the upper end surface of the bearing plate 3 can wear the safety ropes to walk a long distance, thereby ensuring the convenience of the inspectors to check the bottom of the bridge 1.

[0032] The protection assembly 4 includes the blocking vertical rods 41, the blocking horizontal rods 42 and the safety rods 43. A plurality of blocking vertical rods 41 are symmetrically fixedly connected to the front and rear sides of the upper end surface of the bearing plate 3. The blocking horizontal rods 42 are fixedly connected to the top of the blocking vertical rods 41. The plurality of blocking vertical rods 41 can not only support and fix the blocking horizontal rods 42, but also form a guardrail with the blocking horizontal rods 42 to avoid the inspectors walking on the upper end surface of the bearing plate 3 from falling down, thereby improving the use safety of the bearing plate 3.

[0033] The safety rods 43 are fixedly connected to the upper side of the annular side surface of the blocking horizontal rods 42. The safety rods 43 are convenient for the inspectors to connect the safety hooks in the safety ropes with them, thereby further protecting the inspectors on the bearing plate 3 from falling. The safety rods 43 will not hinder the horizontal movement of the safety hooks in the safety ropes, so that the inspectors wearing the safety ropes can walk horizontally on the bearing plate 3 to check the bottom of the bridge 1.

[0034] Embodiment three:

[0035] On the basis of embodiment one, by controlling the work of the servo motor 9, the servo motor 9 can drive the driving walking wheels 8 to rotate. The rotating driving walking wheels 8 can drive the bearing plate 3 to move through the support plates 7 and the connecting columns 6, so that the inspectors standing on the upper end surface of the bearing plate 3 can check other parts of the bottom of the bridge 1.

[0036] The connecting columns 6 are symmetrically fixedly connected to the left and right sides of the upper end surface of the bearing plate 3. The connecting columns 6 are connected with the bearing plate 3 and the support plates 7 by welding. The connecting columns 6 are convenient for connecting the support plates 7 with the bearing plate 3. The connecting columns 6 are provided with the support plates 7 at the top. The support plates 7 can support the servo motor 9 and the driven walking wheels 10. The servo motor 9 is installed on the side edge of the support plate 7. Two groups of servo motors 9 are installed. The two groups of servo motors 9 are of the same specification. The two groups of servo motors 9 are connected with the servo motor 9 driver in parallel through wires. The two groups of servo motors 9 can be controlled by the servo motor 9 controller in speed and position accuracy. The two groups of servo motors 9 can drive the driving walking wheels 8 on the left and right sides to rotate synchronously. Since the internal structure and working principle of the servo motor 9 are mature technologies in the prior art, they are not described in detail here.

[0037] The transmission end of the servo motor 9 is provided with a driving walking wheel 8, and the rear of the driving walking wheel 8 is provided with a driven walking wheel 10. The driving walking wheel 8 and the driven walking wheel 10 enable the bearing plate 3 to be movable. The side of the bridge 1 is provided with a supporting side beam 5, which can support and fix the limiting guide rail 11. The upper end surface of the supporting side beam 5 is fixedly connected with the limiting guide rail 11, and the limiting guide rail 11 is matched with the driving walking wheel 8 and the driven walking wheel 10. The limiting guide rail 11 can limit and guide the driving walking wheel 8 and the driven walking wheel 10, so as to avoid the shaking and deviation of the bearing plate 3 during the movement.

[0038] When it is necessary to inspect the bottom of the bridge 1, the inspector first drills through the guardrails on both sides of the upper end surface of the bridge 1 and enters the inside of the conveying cage 24, then opens the control box and controls the electric hoist 22 to work through the control panel to release the connecting wire rope 23. At this time, the conveying cage 24 drives the inspector inside to descend until the bottom of the conveying cage 24 contacts the bearing plate 3. At this time, the inspector can walk out of the conveying cage 24 and walk to the upper end surface of the bearing plate 3. At this time, the fixedly connected blocking vertical rod 41 and blocking horizontal rod 42 can form a guardrail to block and protect the inspector walking on the upper end surface of the bearing plate 3. Then, the safety hook on the safety rope worn by the inspector is connected with the safety rod 43, so as to further prevent the inspector on the bearing plate 3 from falling, so as to improve the safety of the inspector walking on the upper end surface of the bearing plate 3. After the safety hook on the safety rope is connected with the safety rod, it will not hinder the movement of the inspector walking on the upper end surface of the bearing plate 3, so that the inspector standing on the upper end surface of the bearing plate 3 can walk a long distance while wearing the safety rope. Then, the inspector on the upper end surface of the bearing plate 3 can inspect the bottom of the bridge 1 by means of external inspection instruments. In this process, the inspector only needs to control the two groups of servo motors 9 to rotate synchronously through the servo motor 9 controller in the control box. The two groups of servo motors 9 drive the driving walking wheels 8 on both sides to rotate synchronously in the same direction. The rotating driving walking wheels 8 drive the bearing plate 3 to move through the supporting plate 7 and the connecting column 6, so that the inspector standing on the upper end surface of the bearing plate 3 can inspect other parts of the bottom of the bridge 1. At the same time, the driven walking wheel 10 also rotates, and the counterweight seat 31 can exert a certain downward force on the middle region of the bearing plate 3, so that the bearing plate 3 has better stability during movement.

[0039] When the inspector finishes inspecting the bottom of the bridge 1, the safety hook on the safety rope worn by the inspector is separated from the safety rod 43, then the inspector walks into the conveying cage 24 and controls the electric hoist 22 to wind the connecting wire rope 23, so that the connecting wire rope 23 drives the conveying cage 24 to ascend (for reference Figure 2) so that the transport car 24 can transport the inspector upwards, and when the transport car 24 is raised to the required height, the inspector can walk to the upper end face of the bridge 1 to end the inspection work.
